Seiko Epson and NGK Insulators make quartz microgyro
The sensor boasts unprecedented stability thanks, says Epson, to the use of mono-crystalline quartz for the newly developed gyro element. Combining Epson's original crystal microprocessing technology with a low-power analogue circuit and packaging technology has created a gyro sensor measuring 5.0x3.2x1.3mm, making it the world's smallest gyro-sensor with built-in drive circuitry. The first subminiature angular velocity sensor is designed for use in systems that correct for camera vibrations.
Going forward, the company's efforts will be directed further toward the development of other products using motion detection sensors. Product development efforts will range from game machines, remote-control security devices, at the low end, all the way to navigation systems, attitude-control (gyroscope) applications and similar systems, at the high end.
